Modern wearable sensors for health monitoring are becoming increasingly popular due to their versatility. This study investigates the effects of Co2+ ions in flexible alginate-based composite films with doped cobalt and poly(3,4-ethylene-dioxythiophene):polystyrenesulfonate (PEDOT:PSS) respiratory monitoring. Contrary expectations, Co2+-doped Na-Alg/PEDOT:PSS/Glycerol 3b nanocomposite showed lower LED intensity (168 ± 75 au) conductivity (5.04 × 10-5 S/m). The addition negatively affected electrical performance hindered charge mobility structural integrity. In contrast, Na-Alg/PEDOT:PSS/glycerol 2b film achieved higher (236 25 maximum (6.61 S/m), which can be attributed plasticizing effect glycerol that improves homogeneity transport. also shows excellent wearability on skin, pressure sensitivity, ability monitor respiration.
